Thus, for example, if a lessee makes a prepayment of the first and last years' rent, and it is reasonably expected that the leased property will be export property for the first half of the lease period but not the second half of such period, the amount of the prepayment which represents the first year's rent will be considered qualified export receipts if it would otherwise qualify, whereas the amount of the prepayment which represents the last year's rent will not be considered qualified export receipts.
For purposes of this paragraph, the term "technical assistance or knowhow" includes activities or programs designed to enable business, commerce, industrial establishments, and governmental organizations to acquire or use scientific, architectural, or engineering information.
For purposes of this paragraph, managerial services are considered furnished by a DISC if such services are provided-
Thus, for example, assume that R, S, X, and Y are members of the same controlled group and that X and Y are DISC's. If R sells property to S and pays X a commission relating to that sale and if S sells the same property to an unrelated foreign party and pays Y a commission relating to that sale, the receipts received by X from the sale of such property by R to S will be considered to be derived from Y, a DISC which is a member of the same controlled group as X, and thus will not result in qualified export receipts to X. The receipts received by Y from the sale to an unrelated foreign party may, however, result in qualified export receipts to Y. For another example, if R and S both assign the commissions to X, receipts derived from the sale from R to S will be considered to be derived from X acting as commission agent for S and will not result in qualified export receipts to X. Receipts derived by X from the sale of property by S to an unrelated foreign party, may, however, constitute qualified export receipts.
